| Time period | Development summary |
|---|---|
| 1950s | In the decade comes the development of image intensifier and x-ray television.[1] |
| 1960s | Ultrasound gains popularity.[1] |
| 1970s | The 1970s are known as the "golden decade" of radiology, when the CT scanner opens up new opportunities and discoveries which would be further developed in the following decades.[2] Magnetic resonance imaging develops.[1] |

| Year | Event type | Details | Country/region |
|---|---|---|---|
| 1895 | German physicist Wilhelm Röntgen first discovers the X-ray.[1] | ||
| c.1900 | After learning about Röntgen’s discoveries, American inventor Thomas Edison invents fluoroscopy. Fluoroscopic screens would be then used as an alternation to still x-ray images for some time.[3] | ||
| 1901 | Award | Wilhelm Röntgen is awarded the Nobel Prize in Physics for his contribution to the study of radiation. | |
| 1903 | Lay x-ray operators start being appointed as assistants. | ||
| 1918 | George Eastman introduces film, which would replace radiographs made onto glass photographic plates.[1][3] | ||
| 1920 | Organization | The Society of Radiographers is formed in the United Kingdom as a trade union and professional body for x-ray and radiation technicians.[1][3] | United Kingdom |
| 1958 | Scottish physician Ian Donald develops the first medically used ultrasound to observe the health and growth of fetuses. Donald also uses the ultrasound to study lumps, cysts, and fibroids. Donald, Together with engineer Tom Brown, develop a portable ultrasound machine to be used on patients.[3] | United Kingdom | |
| 1961 | James Robertson, working at the Brookhaven National Laboratory, builds the first single-plane positron emission tomography (PET) scan.[3] | United States | |
| 1971 | English electrical engineer Godfrey Hounsfield builds the prototype computerized tomography (CT) machine, which utilizes both x-rays and computer software to create cross-sectional images of the body. In the same year, the first successful medical scan using this machine is done on a live patient.[3] | United Kingdom | |
| 1972 | The first CT scan is announced.[1] | ||
| 1973 | American chemist Paul Lauterbur develops the way to generate the first two-dimensional and three-dimensional magnetic resonance images (MRIs). In the same year, Lauterbur publishes the first nuclear magnetic resonance image.[3] | United States | |
| 1975 | Frank T Farmer gives an interesting historical review of the physical basis of radiology and demonstrates diffraction patterns as obtained by Von Laue.[4] | ||
| 1975 – 1980 | "Real-time" ultrasound machines are introduced.[1] | ||
| 1977 | English physicist Peter Mansfield of the University of Nottingham describes the general principles of echo-planar imaging.[5] Mansfield develops echo-planar imaging for MRIs by mathematically analyzing the radio signals from magnetic resonance imaging. This development allows for images to be collected much faster than previously possible.[3] | United Kingdom | |
| 1977 | The first human image is obtained through magnetic resonance imaging, in Aberdeen, Scotland.[1] | United Kingdom | |
| 1979 | Award | South African physicist Allan McLeod Cormack and Godfrey Hounsfield are awarded the Nobel Prize in Physiology or Medicine "for the development of computer assisted tomography". | |
| 1985 | Argentine physician Julio Palmaz develops the balloon-expandable stent, thus transforming interventional radiology.[3] | United States | |
| 1998 | "Ronald Nutt and David Townsend invent the PET-CT scan which combines positron emission tomography and computerized tomography in such a way as to make it easier for physicians to locate tumors and other structures on the images. By combining these two scans into one machine, they also made it much easier and less expensive for physicians and hospitals to have access to both forms of technology."[3] | ||
| 2003 | Award | Peter Mansfield shares with Paul Lauterbur the Nobel Prize in Physiology or Medicine, , for discoveries concerning Magnetic Resonance Imaging (MRI) |
